    4. Investigation of methods to extract confocal function parameters for the depth resolved determination of attenuation coefficients using OCT in intralipid samples, titanium oxide phantoms, and in vivo human retinas

      Investigation of methods to extract confocal function parameters for the depth resolved determination of attenuation coefficients using OCT in intralipid samples, titanium oxide phantoms, and in vivo human retinas
      The attenuation coefficient provides a quantitative parameter for tissue characterization and can be calculated from optical coherence tomography (OCT) data, but accurate determination requires compensation for the confocal function. We present extensive measurement series for extraction of the focal plane and the apparent Rayleigh length from the ratios of OCT images acquired with different focus depths and compare these results with two alternative approaches. By acquiring OCT images for a ...

    5. Ganglion cell-inner plexiform layer measurements derived from widefield compared to montaged 9-field optical coherence tomography

      Ganglion cell-inner plexiform layer measurements derived from widefield compared to montaged 9-field optical coherence tomography
      Purpose: To compare ganglion cell-inner plexiform layer (GCIPL) thicknesses obtained using a single WF-OCT scan and standard composite OCT scans acquired in 9 fields of gaze (9F-OCT). Methods: Thirteen healthy participants underwent WF-OCT and 9F-OCT using the Spectralis OCT. The GCIPL was automatically segmented with a manual review for 9F-OCT and was manually segmented for WF-OCT. After registration, differences in GCIPL thicknesses were compared using 95% confidence intervals computed from ...

      Investigation of the lower punctum parameters: A spectral domain anterior segment optical coherence tomography study
      Purpose: To evaluate the dimensions of lower punctum in a sample of Iranian normal population using spectral domain anterior segment optical coherence tomography (OCT). Methods: In this cross-sectional study, 102 eyes of 102 healthy volunteers were enrolled. All participants underwent a detailed history and complete ophthalmic examination. Lower punctum metrics were measured using OCT (Spectralis, Heidelberg) with the anterior segment module. External punctal diameter was defined as the largest diameter ...

    11. Evaluating the Safety of the Spectralis Centaurus Device

      Evaluating the Safety of the Spectralis Centaurus Device
      Optical microsurgery of the retinal pigment epithelium (RPE) requires reliable real-time dosimetry to prevent unwanted overexposure of the neuroretina. The SPECTRALIS CENTAURUS device implements optical coherence tomography (OCT) to detect intentional elimination of RPE cells caused by a prototype laser for selective retina therapy (SRT). Within this clinical trial the safety of the SPECTRALIS CENTAURUS device and its ability to detect RPE cell damage towards selective real-time laser microsurgery will ...

  3. Quotes about Heidelberg Engineering

    1. I am becoming a big fan of spectral-domain OCT, especially Spectralis [Heidelberg Engineering, Vista, Calif.]...To this point with time-domain OCT, I have not been convinced that you can use this technology to follow patients over time. Now, with the faster image acquisition and better axial resolution we see with SD OCT, there is better quantitative peripapillary retinal nerve fiber layer measurement for glaucoma management. The improved accuracy of the OCT segmentation allows for better long-term evaluation of patients.
